Pu-erh tea

„This process was first developed in 1972 by Menghai Tea Factory and Kunming Tea Factory] to imitate the flavor and colour of aged raw pu-erh, and was an adaptation of wet storage techniques being used by merchants to falsify the age of their teas. Mass production of ripened pu'er began in 1975. It can be consumed without further aging, though it can also be stored to "air out" some of the less savoury flavors and aromas acquired during fermentation.“

„Pu'er; 普洱. Also Puerh, Pu - er etc. Pu'er is the modern pinyin spelling. The place name of the Old City of Pu'er through which pack horses transported the tea from Southern Yunnan. The names were recently changed; Pu'er is now Ning Er and nearby Simao has the adopted name of Pu'er. Locally, in spoken Chinese at least, Ning Er is still Pu'er. “
